Heavy-Duty Axle Gears | Premium Power Transmission Components
The forged steel axle gear is a critical transmission component designed to deliver exceptional strength, toughness, and reliability. Unlike cast or welded gears, forged axle gears are produced under high pressure, which refines the internal grain structure of the steel and significantly improves its load-bearing capacity. This results in superior resistance to impact, wear, and fatigue, making it ideal for heavy-duty machinery and long-term operation.
